“…Liu et al [ 100 ] prepared a composite of double‐layer WS 2 and hollow carbon (WS 2 nano‐HS) ( Figure 8 a) by the modified one‐step in situ hydrothermal method. They suggested that HCSs contributed to increase in electrical conductivity and specific surface area and can act as an anode material for Na + storage.…”

In the current age, electric‐driven products based on large‐scale stationary energy‐storage devices, sodium‐ion batteries (SIBs) are good promising candidates due to their comparable low cost, environment friendliness, high efficiency, and relatable huge abundance. An anode plays a vital role in the high performance of rechargeable batteries, so it becomes necessary to focus on the research on high‐performance anode materials. Recently, a number of researchers developed advanced host materials for SIBs to boost their energy density, cycle efficiency, and safety measures. In recent years, nanostructured metal sulfides like MoS2, SnS2, and WS2 with their novel structure‐based anode materials are the focus of the key research in sodium‐storage applications because of their comparable high conductivity, high capacity, good cycle life, and unmatched chemical and physical properties. In addition, these metal sulfides exhibit high mechanical, thermal, and structural stability, which supports them to find their place as an anode material for high‐performance SIBs in large‐scale energy storage production. Herein, the selected metal sulfide‐based nanostructures synthesized by chemical routes are extensively reviewed and their electrochemical properties for application as a high‐performance anode material in the SIBs are explored.

With the enormous development of the electric vehicle market, fast charging battery technology is highly required. However, the slow kinetics and lithium plating under fast charging condition of traditional graphite anode hinder the fast charging capability of lithium‐ion batteries. To develop anode materials with rapid Li‐ions diffusion capability and fast reaction kinetics has received widely attentions. This review summarizes the current status in the exploration of fast charging anode materials, mainly including the critical challenge of achieving fast charging capability, the inherent structures and lithium storage mechanisms of various anode materials, as well as the recent progress to improve the rate performance involving morphology regulation, structure design, surface/interface modification, as well as forming multiphase systems. Finally, the challenges and future directions of developing fast charging Li‐ion batteries are highlighted.

“…Moreover, the presence of weak van der Waals interactions between WS 2 layers, enables it to form graphene-like structures (thin nanosheets), fullerene-like (semispherical or polyhedral) and nanotube (tubular) ones . Actually, several works have reported the preparation and electrode application of 2H-WS 2 (hexagonal) platelets; results demonstrated that 2H-WS 2 has poor electrical conductivity and serious volume variation during cycling, narrowing its practical applications. , …”

Even though WS2 nanotubes (NTs-WS2) have great potential as anode materials for lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs) thanks to their unusual layered structure, their conductivity and cycling stability are far from satisfactory. To tackle these issues, carbon-coated WS2 (NTs-WS2@C) nanocomposites were prepared through a facile synthesis method that involved precipitating a carbon precursor (20% sucrose) on WS2 nanotubes, followed by annealing treatment under an argon environment. Thanks to the presence of highly conductive and mechanically robust carbon on the outer surface, NTs-WS2@C nanocomposites show improved electrochemical performance compared with bare NTs-WS2. After 60 cycles at 80 mA g–1 current density, the cells display high capacities of 305 mAh g–1 in LIBs and 152 mAh g–1 in SIBs, respectively. As the current density increases to 600 mA g–1, it provides specific capacities of 209 and 115 mAh g–1, correspondingly. The enhanced electrochemical performance in LIBs and SIBs is primarily attributed to the synergistic effects of the tubular architecture of WS2, carbon network and stable nanocomposite structure, which can effectively constrain volume variation during the metal ions intercalation/deintercalation processes.
